NHS blood donor specialists calculate that each donation can save the lives of up to three people - meaning Christine and Jim’s simple acts of generosity could have potentially saved hundreds of lives.

The dedicated duo were among 24 donors from across the region - who have collectively made 2, 700 donations - that were presented with awards and certificates from the NHS Blood and Transplant organisation at a ceremony held recently at Wortley Hall in Sheffield.

Christine, who lives in Auckley, said: “I felt really honoured to be recognised alongside all of the other great people who have donated blood.

“I would urge everyone to do it. It only takes about 45 minutes out of your day and you can save peoples lives.

“When I see things on TV about people needing blood, it gives me a good feeling to know that I have done my bit.”

The former national coal board worker first gave blood about 50 years ago before the birth of her daughter Jayne. And all these years on, she still makes time once every four months to donate at Doncaster Racecourse.

Mrs Wooldridge added: “Back then some babies were at risk of ‘blue baby’ syndrome where their body basically rejects some of their blood and as my blood type is 0 Negative it can be used by anyone so I donated as a precaution.

“As it turned out my daughter was born fine without any problems but I just carried on donating.

“It was lovely to receive an award and was great to hear some of the stories of other people. It brought a tear to my eye.”

Blood and organ recipient David Marshall was invited to speak at the ceremony.

The 42-year-old Sheffield man was diagnosed with diabetes when he was aged seven and in his early 30s his kidneys started to fail.

He received a kidney transplant in 2009 but needed blood transfusions due to acute rejection.

The exchanged worked and David made a full recovery.

He said: “Blood and organ donors are real life changers. They are true heroes in every sense.

Mr Rust was not available for interviews at the time of going to press.
